I'm little bit confusion about calculating discount with coupons extrafields.
I'm using latest joomla + joomshopping 4.13. + latest version of coupons extrafields and latest version of Jshop Quick Checkout.
When I put product for 1000 EUR to cart and use standard 10 % discount, in cart I can see 1000 - 100 = 900 €. But when you go to checkout, there is address, shipping and payment in one sigle page. When you change the shipping (with other shipping price) discount not changing but it is calculated from "default" shipping price.
It is possible to set, that shipping price is not including to discount?
